Meet Dewey, the environment management robot. Originally named for Melvil Dewey, (of the Dewey Decimal System), we decided the bot from Silent Running makes a better mascot.
It's also appropriate, since Dewey is a loyal robot, who is seen all alone at the end of the movie, caring for the environment (a forest greenhouse on a space ship), holding a battered old watering can as he drifts deeper into space.
Dewey is designed to be the canonical source of information about your computing environments. A computing environment consists of hosts, clusters, and other resources, and is built on top of networks and hardware. Dewey lets you store, model, and manage all of this information, from rack to virtual machine.
On top of this model, Dewey will automate provisioning of virtual machines into different environments, with role-based access controls per environment. The initial provisioning integration will be with saltstack/salt-cloud, but other integrations will be possible.
Unlike OpenNMS and other discovery-based management solutions, Dewey is designed around defining what your environments should look like, not discovering what's out there.
Dewey is suitable for integrating with configuration management systems like saltstack, and salt integration is a major focus of the project. At PLOS, Dewey provides an external pillar for salt, which defines all hosts and their roles.
Dewey is a Django application that leverages django-rest-framework for providing a rest interface. No further interface is currently defined, but an HTML frontend could be easily implemented.
Dewey is developed against python-3.2 and django-1.8. To get started, you must first install python.
Once you have a working python, set up a virtual environment for containing its dependencies:
pyvenv ~/.virtualenvs/dewey
Export the environment variables required for configuration by appending the
following to ~/.virtualenvs/dewey/bin/activate:
# set the Django settings module (more on this in a moment)
export DJANGO_SETTINGS_MODULE="dewey.settings.chaumes"
export SECRET_KEY='somereallylongrandomstringwithpunctuationandstuff'
export POSTGRES_PASSWORD='secret!'
# needed for syncing with Ephor asset tracker
export JIRA_USERNAME='joesixpack'
export JIRA_PASSWORD='drinkspbr'
